I think they need the music to have its own director. I love the fact that they have the original themes, but each one seemed to last a few seconds before switching to the next one (unlike, say, Ace's theme in Ultra Fight Victory, which I think played through the entire song). I liked the bit of dialogue between Seven and Zero near the end, though it feels like a missed opportunity when Orb used a form that borrowed Zero's power without Zero commenting on it.
